This is the VEN/DEV under hardware ID's.
I tried to use the Intel Driver and Support Assistant but unfortunately it didn't detect me missing anything.
First of all, IDSA is not intended for use on discontinued boards.
You can resolve this device entry by updating the Intel Chipset Device Software package and installing the Intel Management Engine driver package. The versions for your board can be downloaded from here: https://downloadcenter.intel.com/download/22153/Intel-Chipset-Device-Software-for-6-Series-Chipset-B... and here: https://downloadcenter.intel.com/download/20584/Intel-Management-Engine-Driver-5M-for-Intel-Desktop-....
Now, you will notice that these packages do not support installation on Windows 10. That is because Windows 10 is not supported on this board. If you are running Windows 10 and having these problems, then I am sorry but you are stuck with them.
Hope this helps,
